Detailed description of the invention
The present invention provides the earphone tonequality of a kind of mobile terminal to improve method and system, and for making the purpose of the present invention, technical scheme and advantage clearly, clearly, developing simultaneously referring to accompanying drawing, the present invention is described in more detail for embodiment. Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
Refer to the earphone tonequality that Fig. 1, Fig. 1 are mobile terminal provided by the invention and improve the flow chart of method preferred embodiment, as it can be seen, said method comprising the steps of:
Step S100, the earphone sound channel current reference value of mobile terminal is set;
Step S200, detection mobile terminal earphone sound channel current value;
Step S300, judge that whether described earphone sound channel current value and earphone sound channel current reference value be identical, magnitude of voltage that mobile terminal powers to earphone sound channel is regulated so that the earphone sound channel current value detected is identical with earphone sound channel current reference value if it is different, then corresponding.
Below in conjunction with specific embodiment, above-mentioned steps is described in detail.
In the step s 100, the earphone sound channel current reference value of mobile terminal is set. Specifically, described mobile terminal is the terminals such as mobile phone, panel computer, handheld device. These mobile terminals all have receiver J-Horner, and user can be inserted into earphone and listens song or voice-enabled chat etc. The earphone sound channel current reference value of mobile terminal is set, specifically can pass through to measure in advance the earphone sound channel current value of (or in tonequality preferably situation) under normal use correspondence of mobile terminal, in this, as earphone sound channel current reference value. Preferably, headset left channel and earphone R channel is included due to earphone sound channel, corresponding then have the current value of two sound channels, thus the headset left channel of mobile terminal and earphone R channel specifically can be respectively provided with the current reference value of correspondence by the present invention, in order to follow-up respectively two sound channels are carried out voltage-regulation.

Preferably, described step S302 specifically includes:
S321, judge that whether described earphone sound channel current value and earphone sound channel current reference value be identical, if described earphone sound channel current value is more than earphone sound channel current reference value, then reduce the magnitude of voltage that mobile terminal is powered to earphone sound channel, and return step S200, wherein, the magnitude of voltage of reduction is the first scheduled voltage; If described earphone sound channel current value is less than earphone sound channel current reference value, then raising the magnitude of voltage that mobile terminal is powered to earphone sound channel, and return step S200, wherein, the magnitude of voltage of rising is the second scheduled voltage; If identical, then keep the magnitude of voltage that mobile terminal is powered to earphone sound channel constant.
Specifically, reduce the magnitude of voltage that mobile terminal is powered to earphone sound channel, the magnitude of voltage every time reduced is the first scheduled voltage, such as 0.1V, for example, if described earphone sound channel current value is more than earphone sound channel current reference value, so reducing the magnitude of voltage that mobile terminal is powered to earphone sound channel, magnitude of voltage originally is 3V, then reduces to now 2.9V, perform step S200 again, continue to judge. In like manner, described second scheduled voltage is the voltage definite value increased, it is possible to be set to 0.1V. Identical can differ about the first scheduled voltage and the second scheduled voltage, specifically can be configured according to actual needs.
Preferably, described earphone sound channel includes headset left channel and earphone R channel.
